Provide preferred embodiment of the present invention according to Fig. 2 below, and, further provide ins and outs of the present invention, make it that specific implementation process of the method that provides of the present invention can be described better in conjunction with description to embodiment.
The embodiment of the invention proposes a kind ofly to select the soft replacement method of network in migration zone, the core concept of this method to be based on flow, installs new equipment before network is replaced, the newly-built one network B that throws the net on the basis of old network A.In whole network replacement process, used equipment originally need not be removed, and old network A can provide service always.New used equipment exists simultaneously, and new and old two two nets of throwing the net are runed simultaneously.By select the big and big migration zone of flow of several telephone traffics on old network A, the parameter of revising old network A in the certain hour window forces the user who enters the migration zone to move to new network B.Like this user in the old network A is progressively caught up with into new network B, migrates into new network B up to all users, wait new network B run all normal after, old network A outage is removed.
Elaborate the soft replacement implementation procedure of network below, the system's network element that relates in the method that the embodiment of the invention provides has: the RNC of wireless side (Radio Network Controller, radio network controller) and NodeB (Node B, WCDMA system base-station); The VLR of core-network side (Visiting LocationRegister, Visited Location Registor).
Concrete implementation procedure comprises:
One, before network is replaced, carry out following operation:
(1) the newly-built one network B that throws the net, and after network-wide optimization is finished, " not reserved " (non-reservation) is arranged in new network B the whole network sub-district.
Wherein, new network B is used identical PLMN (Public Land Mobile Network, public land mobile network), i.e. user's HPLMN (Home PLMN, Home Public Land Mobile Network network) with old network A;
The core network element VLR of old network A and new network B needs different, and other core network elements are not limited, both can be identical, and also can be inequality.
(2), in old network A, choose at least one migration zone according to default selection standard.
Wherein, comprise one or more sub-districts in each migration zone; Default selection standard is preferably set by following constraints: distribute and mobility status according to country and city traffic, it is big to choose telephone traffic, flow is big, the many and strong zone (for example, customs's mouth, railway station, subway station, harbour and trade area etc.) of user mobility of number of users.What this zone was preferable should be distributed in different place (mainly being the geographical features according to national city).
Wherein, the telephone traffic in migration zone is added up with cell-level, chooses some higher sub-districts of numerical value.
(3) in selected migration zone, configuration is the alien frequencies adjacent area of the sub-district of old network A with the sub-district of the affiliated new network B that the base station is identical, the geographical position is identical in sub-district of old network A.
(4) formulate flow migration plan table according to the total flow situation of old network A the whole network, thus the flow of the each migration of control.
The PS numeric field data flow that comprises the CS territory telephone traffic and the different migration phase correspondences of different migration phase correspondences in this flow migration plan table, more preferred, can also comprise in this flow migration plan table: the number of users to be migrated of different migration phase correspondences, different migration phase corresponding service ratio and total business and signaling traffic.Wherein, number of users, business proportion and business and signaling traffic can by CS territory telephone traffic and PS numeric field data flow push away (this computational process belongs to prior art).
As shown in Table 1, be that a concrete flow migration plan is represented example, divided 6 stages to move in this example, the flow of the new network B of can moving into when just beginning is littler, thereby formulates rational time window duration.Certainly migration phase can be divided according to the total flow situation of old network A, when total flow is big, can be made as a plurality of, when total flow hour, also can only be set a stage.
In the table, the number of users, the 3rd that first different phase, second of classifying division as is classified the different phase correspondence as is classified different phase corresponding service ratio, the 4th as and is classified the CS territory telephone traffic, the 5th of different phase correspondence as and classify the PS numeric field data flow, the 6th of different phase correspondence as and classify total business and signaling traffic as.Owing to can observe the traffic carrying capacity of current migration more intuitively, in the soft replacement process of following network,, judge whether to reach the traffic carrying capacity of this migration by observing the migrated users number that whether reaches the current generation setting by the observation number of users.
Table one
Two, in network is replaced, carry out following operation:
(1) in selected migration zone, reduce the value of the quality offset parameter of old network A sub-district, for example, revising cell quality biasing Qoffset is-30dB to force the user to move to new network B.
Simultaneously, real-time monitored is moved to the number of users of new network B in the VLR of new network B, thereby assesses suitable time window length, so the length of this time window is not a definite value, has different length according to this time window of different situations.When in migration (in the error allowed band the approximate satisfied) table one that advances that number of users satisfies in the new network B during to the requiring of current migration phase, change back original value the cell quality offset parameter of old network A sub-district in the migration zone, time window is closed, after time window is closed, between old network A and the new network B without any interactive operation.
Wherein, the unlatching of time window starts from the modification of quality offset parameter value, time window close the end that terminates in the current generation, and the length of time window is by the telephone traffic decision of locality, purpose is to impact to new network B.
(2) repeated execution of steps (1), each stage is all put into the number of users of plan, all moves to new network B up to all users.
As shown in Figure 2, move to migration schematic diagram in the new network B for old network A sub-district in the migration zone in the embodiment of the invention, this schematic diagram is that example describes to choose two migration zones.Among the figure, the sub-district in the migration zone can carry out switching or reselection operation with frequency, and the sub-district of moving to new network B also can be carried out with switching frequently or reselection operation, so the user is moving zone and nonmigratory professional impression without any influence.But the sub-district in the new network B is re eligible or switch back old network A not.
Need to prove that also there are special circumstances in above-mentioned network replacement process, for example,, when but no longer increasing, illustrate that some user in the old network A did not enter the migration zone if the customer volume in the new network B of follow-up phase does not also reach 100%.Have two kinds of processing methods this moment: 1) when remaining user is also many in the old network A, and zone user mobility difference many number of users also is set to the migration zone, with above-mentioned moving method these users moved in the new network B; 2) when remaining user was fewer in the old network A, old network A was directly cut off the power supply, and all users enter new network B like this, and can't cause too big influence this moment to new network B.
Further, in each transition process, the user who enters the non-special-purpose attitude in migration zone can enter new network B; Still stay in the old network A and move the special-purpose attitude user in zone and do not enter the regional user of migration.
After the user enters new network B, can in new network B, move arbitrarily, be distributed in network Anywhere, carry out the business that various operators provide.And because migration zone chooses is that user mobility is big, the zone that flow is big is so after the user enters new network B, can be distributed to other zones of new network B rapidly.And, also allow them to enjoy service in new network B for not by migration zone and the resident roamer of time window, manual network selection user or other users to new network B.
Three, after the user was moved to new network B, the device powers down of old network A was moved back clothes and dismounting.
The method that the embodiment of the invention provides, the problem of service can not be provided for the user in having solved when new and old network is replaced in short-term, further, this method can also produce impact thereby avoided all users to move to new network at short notice simultaneously to new network by the service traffics of control migration; And method provided by the invention makes operator have a PLMN to get final product, and does not need to provide other PLMN again; Operator does not need the website to the whole network to carry out matched adjacent zone or changes the operation of parameter, only needs several migration zones of control to get final product, and has reduced workload like this, has saved manpower; And, if the problem that new network occurs, all users can get back to rapidly in the original old network, and rollback is easy, almost there is not risk for operator and equipment vendor, the user does not have sensation substantially, and in whole network replacement process, extensive work can be finished before the user moves, only need in the transition process to change individual parameters and monitor to get final product, save time and manpower, error probability is little, and risk is little.
The present invention also provides a kind of network based on flow control soft alternative, as shown in Figure 3, comprising:
Network is replaced unit 310 is set, and is used for after new network is set up, and according to default selection principle, chooses one or more migrations zone in old network, and formulates flow migration plan table according to the total flow of old network;
Network is replaced performance element 330, is used for monitor in real time the newly-increased traffic carrying capacity of new network, when in this traffic carrying capacity satisfies flow migration plan table the qualification of current migration phase being required, the quality offset parameter value of the regional interior sub-district of migration is revised back initial value.
Further, this device also comprises:
Further, comprise N migration phase in the above-mentioned flow migration plan table, described N is a positive integer.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
